BRAIDING MACHINE.

Application filed December 16, 1922.

To all whom it may concern:

Be it known that I, EDWARD K. STANDISH,

a citizen of the United States, residing at Dorchester, in the county of Suffolk and the State of Massachusetts, have invented a new and useful Improved type of Braiding Machine, of which the following is a specification.

This invention relates to an improved machine for making braid and as disclosed herewith is of the rotary type, having separate thread or yarn supplies moving in opposite directions, with means whereby. the yarn from the outer, or in this case the lower, set of yarn supplies may be passed on either side of the inner or upper set of oppositely moving yarn supplies, at a very high speed of rotation.

Other objects obtained are simplicity of 0 design and cheapness of construction, lower power and maintenance cost, small fioor space, and a positive control of the yarn at all times.

More specifically there is disclosed a new drive for the inner shuttles, which is capable of high speed'and which while positively passing yarn from the outer carriers does not subject said yarn to pressure or stretch.

There is also disclosed a method of passing one thread by the other where threads are angled over a lip, which makes possible the placing of the diiferent sets of yarn supplies one above the other.

There is also disclosed means for more accurate thread or yarn control, a new and simpler type of take-up mechanism, and a friction braking means for the yarn feed in combination with a simple positive latch to,

hold the yarn spool or package in the yarn to carrier and to permit instant removal.

These and other features of the invention 4 Serial No. 607,429.

Fi 2 is a top view of the machine showing t e thread fingers, thread finger cam, and take-up mechanism.

Fig. 3 shows sections of the machine as viewed from above. The left side being a cross section on line AFig. 1and the right side being a cross section on line B- Fig. 1.

Fig. 4 discloses a large plan view in some detail of the inner or upper yarn supply carrier drive mechanism.

Fig. 5 discloses a side view of the driving means shown in Fig. 4 and Fig. 1, and partly in section through line E E, Fig. 10a

Fig. 6 discloses a difi'erent type of driving roller than that shown in Fig. 5.

Fig. 7 is a side elevation partly in section of the take-up mechanism.

Fig. 8 discloses a detailed view in elevation of the inner carrier together with an improved type of a combined friction yarn release and a positive latch to hold the yarn supply package or spool to its carrier.

Fig. 9 1s a plan view of a carrier as from line D D-Fig. 8.

Fig. 10. is a plan view of one-half of the yarn clearing plate 27.

Fig. 11 is an end view, in elevation, of the method of adjusting the friction yarn release shown in Figs. 8 and 9.

Similar numerals refer to similar parts throughout the drawings.

The machine as disclosed is resting on the bench or table 1, the base 2 being suitable for this purpose, orfor attaching to the common type of floor leg.

This base or casting 2 is pot shaped. and forms an oil reservoir in which most of the gearing turns, and from its center rises a post 3 shown herewithas part of the base 2, but which may be of tubing suitably attached. The post 3 has a central hole 4: through which may be carried a core to be braided upon.

Rotating about the central post 3 on bearings 48 and 66 is the member 5 which carries the outer, or lower, set of thread or yarn supplies 12 on its outer and lower horizontal surface. The member 5 slants inward and downward and has, as a part of, or attached thereto, the bevel gear 54 and carries the spur gearing 61 and 62.

The member 5 also has an upwardly extending tube to which is attached the wheel 6, and above this the cone-shaped pan 93.

To the outer and lower horizontal surface of 5 is attached a metal cylinder 11 which in turn carries a plate'7, which in turn carries upwardly extending rods or bars 8 and 9 suitably tied together at the top as by the hoops 10.

It will thus be seen that when the member 5 is rotated it carries, rigidly connected therewith, means both inside and outside of the inner or upper yarn supply 13, to control the yarn from the outer supplies.

As mentioned, the spur gearing 61 and 62 is carried around by the member 5 and rotates on the shaft 68 as a unit.

The spur gear 62 is in mesh with the spur gear 64 which is rigidly fastened to the base 2. v

The spur gear 61 is in mesh with the spu gear 65 on the lower end of an upwardly extending tube 20, which has bearings 21 and 22, and outwardly extending arms carrying bearings 17.

The ratio of the gears 62 and 64, 61 and 65, is such that one revolution of the outer supplies 12 and the member 5 in a clockwise direction, as viewed from the top of the machine, will turn the member 20 and the arms and bearings 17 one revolution anti-clockwise.

The bearings 17 hold a shaft 16 having a pinion 18 on its lower end, said pinion meshing with the internal gear 19.

At the upper end of the shaft 16 is a roller 15, a disc 33and a plate 27. The plate 27 as shown, is attached to the arms of the member 20 but if desired may be made a partof this member.

When the arms and bearings 17 are rotated, the roller 15 pushes the roller 23 which is attached to the inner yarn supply carrier 14 and forces said carrier to rotate about the central post 3 of the machine in a direction opposite to that of the outer yarn supplies 12 and the member 5 and wheel 6, which rotate as a unit about said central post 3.

Yarn from the outer supplies 12 is carried first to a suitable holding point 51, which may be movable, and from there inside the outer stationary cam plate 28, and through a narrow slot 92, Figs. 1 and 3 cut radially from the center of the machine in the plate 7, past the forward or advance side, or in a slot, of the rod or bar 8 and 9, inside the outer stationary camplate 29, over the lip of the cone shaped pan 93, to the braiding point 50, consisting of a bar with a hole therein suitably supported by the rod 52 from the take-up bracket 74.

All of the above mentioned slots, rods or bars, below the braiding point, and the pan 93 rotate as a unit with the yarn supply 12 and help to maintain the yarn in line when said yarn passes on the outside of the inner supply carrier 14.

For the purpose of allowing this yarn to pass inside said inner carriers 14, the wheel 6 is also provided with radial slots 91, as shown in Fig. 3, left side, and a slotted plate rod or bar 40 may be attached to the cone-shape pan 93.

The rod or bar -'8- below the inner packages 13 may be suitably attached to the rod or bar 9-. The bar -9- is shown as being fastened. to the plate 7 but may be carried inward and suitably fastened to the metal cylinder -11-.

The bar 8 extends inward so as to overlap the wheel 6-, and has a pushing or guiding edge which is at all times in line with a similar edge of the slot -91- in the wheel 6-.

The plate 7 under the wheel 6- also has a guiding edge similarly located with reference to the slot -91--.

The bar -9 has its upper end above the package 13, and this end has a portion extending inward beyond a vertical line dropped from the forward end of the guide bar 39-, so as to push or guide the yarn from the outer supplies after it has been left on the guide bar 39-, by the reciprocating fingers 1l.

The bar 9- extends inward sufliciently far so that it will be overlapped by the reciprocating fingers 11- when said fingers are in their outer position; and also so that it will overlap the plate 1O, which also has a similarly located guiding edge.

By thus overlapping the various members a continuous and substantially radial edge is provided to guide and push the yarns coming from the outer supplies:

In practice the yarn from the outer supplies will not remain in line between the holding point 51- and the braiding point.

Because of the speed of the machine, the windage, the light tensions required, and the drag which occurs at every point of contact, it is necessary 'to push the yarn at several places between said holding and braiding points.

As all of the above radially located edges of the various members are in effect fastened to the same member --5- and rotate therewith, it will be seen that yarns from said outer supplies areheld to a close alignment.

The cam plates 28 and 29 are supported at suitable points by rods 38 fastened to the base 2--lFig. 1.

The method disclosed for driving the inner yarn supply carriers, by the rolls 15 and 23, offers a means for obtaining much higher rotating speeds than is possible with the more familiar forms of reciprocating dog drives, but the pressure between the rollers is suflicient to damage certain grades of yarn.

To overcome this objection slots or grooves are introduced in either the driver or driven roller and proper feeding and clearing means provided as disclosed more fully in Figures 4. 5 or 6.

The roller 15, Fig. 5, has its outerperi hery cut with a. large number of small ots or grooves having sufiiciently wide lands between to offer a practically continuous surface for the pressure of the opposite or contacting roller 23.

Due to a tendency of the thread to drag against the deflecting plates 30, Fig. 1, which are carried on, or a part of, the inner carrier 14. it is found advisable to make said slots wedge shaped. as shown in Fig. 5, 37, or where necessary the slots may be crossed as at 35, Fig. 6, and the face of the roller beveled where desired that the axis of the slotted roller, and of the contacting roller, shall not be parallel.

In order that the yarn may be forced into the slots 34, there is provided with the roller 15, a flange or disc 33 rotating therewith and of larger diameter than the roller 15.

This flange or disc 33 may be made a part of roller 15 or separate and fastened thereto as by screws 53; and is also provided with slots corresponding in number to those in the roller 15, but preferably made slightly narrower. and preferably having a straight forward face and a receding rear face, as shown at 36, Fig. 4. The slotted rollers have a higher peripheral speed than the yarn.

When the yarn from the outer supplies 12 is inwardly deflected by the cam plates 28 and 29, it passes inside the forward point 94 of the deflecting plate 30 on the inner supply carrier 14 and is immediately, because of the higher peripheral speed of the roller, picked up and forced to slip into the slots of the disc 33 and thus guided into the slots 34 of the roller 15, and passes under the contacting edges of the rollers 23 without being subject to pressure.

A like action occurs as the yarn passes out from the rear end of the innercarriers.

In order that this yarn may be positively cleared from the rollers and discs after passing the pressure lines there is provided a plate 27. Figs. 4 and 5. and where necessary a plate 49. These plates are suitably attached to the arms of the member 20 which carrv the bearings 17 and rotates therewith about the center post 3, thus maintaining a constant position with respect to the roller 15.

The plate 27 has a cam shaped surface adapted to feed the thread into and out of the slots of the rollers and discs, and the plate 49 has substantially the same contour.

In order that the outside diameter of the moving parts of the machine may be as small as possible for high speed it is thought desirable to mount one set of yarn supplies above the other.

This construction makes necessary an angle in the yarn between the point of supply 51 and the braiding point 50.

In order to lift the yarn from the outer supplies at times over the yarn from the inner supplies at thi point and to assure a positive control of said outer yarn at this point so that it may bepositively placed in a position to pass outside the inner yarn supplies there is attached to the post 3, Fig. 1, a stationary head 45 held on by the nut 47.

A cam groove 44, Fig. 2, is cut around the outer edge of this head 45, and protected by a plate 46, Fig. 1.

The cone shaped pan 93 carries on its outer edge preferably a. series of fingers 41 pivoted at 42, Fig. 2, saidfingers being oscillated by rods 43 attached to rollers in the cam slot 44.

Attached to the deflecting plate 31, Fig. 1, which is carried on the inner yarn supply carrier 14 by the rods 32, is a guide bar 39 having a T-shaped head over which the yarn from the outer supplies may slide when it passes outside the inner carriers.

When the yarn from the outer supplies is to pass inside the inner supplies the fingers 41 are in a position practically flush with the outer periphery of the cone shaped pan 93 and the yarn is forced inward by the sinuous inner edge or cam surface of the plates 28 and 29.

' When the yarn from the outer supplies is to pass outside the inner carriers the finger 41 moves outward in time to lift the yarn outside the outer edge of the guide bar 39, and because of the location of the holding point 51, Fig. 1. with reference to the forward point 94. Fig. 4, of the defleeting plates 30 and 31. and of the clearing action of the plate 27. Fig. 4, the said yarn throughout its entire length will also pass outside said inner carriers.

The action of finger 41 atthis time also helps to compensate for the change in length of the yarn between points 50 and 51.

When the finger 41 leaves the yarn from the outer supplies resting on the guide bar 39 it is in advance of the rod 9, and as the finger 41 retracts to pass under the yarn from the inner supplies the rod 9, which is located as close to the bar 39 as possible, continues to force the outer yarn forward, thus preventing said yarn from dragging and lengthening.

Yarn 96-Figs. 1 and 8-from the inner yarn supply is carried through the eyelet 100 and through the hole 97 in the plate 31 to the hole 95Fig. 1-in the T-head of the guide bar 39and thence to the braiding point,

In order to secure an easy running inner carrier which will maintain accurate alignment, the inner face of the rim of the wheel 6Fig. 1is provided with annular grooves and the outer face has an annular lip 26.

The inner carrier 14. preferably has two upper rollers 25 and two lower rollers 24 adapted to run in said grooves of the wheel 6 and a slot adapted to fit the annular lip 26, and also carries the driven roller 23.

The driven roller 23, Fig. 8, may have a lower roller 98 attached thereto and rotating therewith on the stud 90. This roller 98 acts to'steady the upper end of the cylinder 11 and also helps to drive roller 23.

The member 5 is driven by a pinion meshing with the bevel gear 51 attached thereto.

The pinion 55 is on the shaft 56 rotating in a bearing in the base 2 and is driven by a belt on the pulley 58.

The pulley 58 has on its inner face a clutch 57 held in place by the spring 50, but which may be disengaged by moving the handle 00, Fig. 2. which has a yoked inner end to move the collar 60 on the hub of the clutch 57.

The take-up mechanism as shown in Figs. 1, 2, and 7, comprises a pinion 67 meshing with the gear 54 on the member 5. This pinion 67 is on a shaft 68 carrying a worm 70 which in turn meshes with a worm Wheel 71 attached to a vertical shaft 72.

The upper portion of the take-up mechanism is supported by a tube 73 carrying on its upper end a suitable bracket 74 which may be swivelcd on the tube 73 to allow of dismantling the machine, but is normally clamped by a bolt at 75.

This bracket 74 is open at the rear end to provide access to the bevel gears 7 6, one of which is attached by a spline to the upper end of shaft 72 so that it may be slid up or down said shaft.

The driven bevel gear 76 is on a short horizontal shaft carried on a bracket 77. Above the bevel pinions 76 is a shaft having a spur gear 79 on its rear end which meshes with a spur gear78 on the bevel pinion shaft.

These spur gears are intended to be changed at will. thereby changing the speed of take-up and the number of picks per inch of braid. This is accomplished by raising or lowering the bracket 77 on the rod 69.

The shaft 80 extends outward and carries a beve pinion 81 meshing with a bevel gear 87 on the take-up drum wheel 88.

At the outer end of shaft 80 is a short right angle shaft carrying a spur gear 83 and driven by slidably mounted bevel pinions 82. The spur gear 83 meshes with the lower of two spur gears 84 which are at tached to shafts carrying knurled rolls 85,

assume the upper of which is pressed downward by a weighted lever 86.

Braid made at the point 50 is passed around the drum wheel 88, thence over the small idler 89 and forward between the knurled rolls to a suitable receptacle.

This construction permits the braid to be stretched before delivery, and odors little obstruction to the operators use of the machine.

Tn order that the yarn tensions may be changed and to provide a simple, quick and positive lock for the yarn supply package to the carrier 14:, there is disclosed the construction shown in Figs. 8 and 9.

The plate 30 on the carrier 14 has attached thereto rods 32 extending between the plates 30 and 31.

The plates 30 and 31 are each provided with a centrally located notch 101 preferably tapering, and adapted to hold the ends 102 of a suitable core for the yarn package 13.

Back of the yarn package 13 is a curved plate 103 which is pressed against the package by the action of the spring 10 1, thus causing friction to retard the turning of said package.

One of the supporting rods 32 is enclosed by a removable sectional sleeve consisting of the tubes 107 and 108, see Figs. 8 and 11.

Slidably mounted in the plates 30, 81, are bars 105 having a beveled inner end as shown at 101, Fig. 9.

The outer end of these bars has a hole in which is the pin 106 which is securely fastlcgged to projecting end of the tubes 107 and These tubes are separate for purposes of assembly and are tongued and grooved to each other as at 109 and thus turn in unison.

Fastened or made a part of the curved plate 103 is a tube 110 adapted to slip over the tube 107.

A collar 111 having a number of grooves 112 is slipped over the tube 108.

The pin 106 on the tube 108 extends through the projecting end of said tube and fits into one of the grooves 112 in collar 111.

A pin 113 located in the projecting end of the tube 107 but slightly nearer its center than the pin 106 extends into a segmental slot 114 in the enlarged portion of the tube 110. One end of spring 104 is under the curved plate 103 and the other end is bent to fit in the slots 112 of the collar 111.

Upon rotation of the tubes 107. 105, the bars 105 are moved in or out simultaneously.

As the spring 104: is coiled it causes the bars 105 to press inward and the curved plate 103 to press outward.

When the package 13 is forced into place the core ends 102, acting on the bevel surface of the bars 105, force them out and the package slips into place, at the same time pressing against the plate 103.

By rotating the collar 111 the package is released, and by raising the collar 111 from the pin 106 and rotating, the spring may be adjusted.

'hen the package isout the curved plate 103 would swing completely around but for the pin 113 in the segmental slot 114 of the tube 110.,

Automatic stopping means are employed in this machine but as they form no part of the present invention, they will not be described.
